FAA landing limits could delay 25% of inbound flights at San Francisco International Airport

Disruption overview

A permanent FAA rule at San Francisco International Airport has cut the airport's arrival rate from 54 to 36 flights per hour, with around 25% of inbound flights now expected to arrive at least 30 minutes late through the spring and summer peak. The restriction comes on top of runway resurfacing that began on 30 March 2026, and some passengers may face delays before departure as flights are held at other airports to match the slower arrival flow into San Francisco. While widespread cancellations haven't been reported, the reduced capacity leaves little room for airlines to recover from further disruption. Because the delays are tied to a safety mandate and construction outside airline control, compensation under EC 261 is usually unlikely, but airlines should still help with rebooking, refunds, and care during long waits.

Disruption details

Passengers flying into San Francisco International Airport can expect ongoing delays after the FAA permanently tightened landing procedures, cutting the airport's maximum arrival rate from 54 flights per hour to 36 flights per hour. The change was announced on 31 March 2026 and now applies in clear weather as well as poor weather.

For passengers, this means longer waits in the air and on the ground. Airport officials now expect about 25% of inbound flights to be delayed by at least 30 minutes through the spring and summer peak, as planes are spaced farther apart before landing.

The pressure is even greater because Runway 1 Right/19 Left closed for a six-month resurfacing project on 30 March 2026. Construction alone was expected to slow arrivals, but the FAA's new rule has added another constraint on top of that.

Here's what travelers should expect at SFO:

• The airport can now handle about 36 arrivals an hour instead of the historical 54.

• When the runway work ends in early October, capacity should rise only to about 45 arrivals an hour, and the FAA limit will still stay in place.

• No widespread cancellations have been reported, but there is much less room to recover when weather or other operational issues appear.

The FAA says SFO's parallel runways are only 750 feet apart, which means the side-by-side visual approaches used for years no longer meet national separation standards. Those simultaneous approaches were already restricted in bad weather. Now the same limit stays in place even when visibility is good, and it isn't tied to the construction project.

This matters especially for United Airlines, which carries roughly half of SFO's passenger traffic, and Alaska Airlines, the airport's second-largest carrier. Both airlines are reviewing their schedules, but neither has announced flight cuts.

Some delays may begin before you even leave for San Francisco. Airlines are already using ground-delay programs that hold departures at other airports so flights reach SFO at the slower, regulated pace. That can create knock-on delays across wider networks, especially when aircraft are scheduled to turn around quickly after landing.

Because these delays are being driven by an FAA safety measure and runway work outside the airline's control, compensation under EC 261 is unlikely in most cases. Still, if your trip is disrupted, your airline should offer practical support, including rebooking or, if your flight is canceled, a refund, plus food, drinks, accommodation, and communication help when the delay is long enough.

Although compensation is unlikely here, that doesn't mean you're without support. If your flight to or from SFO is delayed, AirHelp's free flight checker is a simple way to understand what rights may apply and what support to ask for.
